Cause: Neurological Problems and Medical Disorders
People with conditions that cause nerve dysfunctions may experience charley horses. Parkinson's disease, nerve compression in the lower back and neuropathy are examples of these types of neurological issues.3Publishing, Harvard Health. ‘Take That, Muscle Cramps!’ Harvard Health, www.health.harvard.edu/staying-healthy/take-that-muscle-cramps.
People with hypothyroidism, a condition in which the thyroid gland produces insufficient levels of thyroid hormones, may also experience frequent charley horse episodes. Pregnant women may develop muscle spasms as electrolyte levels fluctuate, circulation changes and the fetus puts pressure on nerves as it grows.2‘Muscle Cramps.’ Cleveland Clinic, my.clevelandclinic.org/health/symptoms/21190-muscle-cramps.
